Nature Trek: A Glacial Perspective

Illinois

Learn how glaciers helped form the Illinois River Valley. 

Join us on Saturday, January 26 to learn how the last Ice Age shaped the present-day landscape. Participants will meet at our Illinois Rivers Program Office, located at 11304 N. Prairie Road in Lewistown, Illinois. A brief tour of the LEED-certified facility will be included in the morning's activities. Attendees must dress appropriately for the outdoors, provide their own drinks and snacks and be able to hike comfortably with an elevation gain and across uneven terrain. Some light refreshments will be served.
